Self-excite
verb ·Rare ·Advanced level
Definitions
- 1 To energize or excite (the field magnets of a dynamo) by induction from the residual magnetism of its cores, leading all or a part of the current thus produced through the field-magnet coils.
"Using metal rollers to simulate the earth's cylindrical eddy currents, the team found some interesting results after beginning with a few viscosity problems. "...a more efficient geometry was found, so efficient that the dynamo would self-excite in a completely homogeneous state (i.e. with no insulation ) at a much lower rotor speed than was believed possible" [12] ."
- 2 To self-generate a state of excitation.
"Thus warning systems can self-excite when they go on alert: When a decision maker thinks that an attack is likely, he will place more credence in reports indicating that a war is imminent than he would if the same information were received in a period of calm, and actions of the other side that usually would be missed or seen as innocent will be perceived as evincing hostile intentions."
